Portable electric load bank apparatus, system, and method of operation

ABSTRACT

This disclosure presents a portable load bank apparatus, system, method of control, and method of manufacture. A portable load bank apparatus may comprise one or more of a vehicle, a load bank, a set of batteries, a set of battery chargers, one or more processors, and/or other components. The load bank may be configured to perform a load test of an external power source. The processor(s) may be configured to cause one or more battery chargers in the set of battery chargers to direct an amount of a power output received by the load bank from the external power source to the set of batteries. The set of batteries may be used to provide electrical energy to one or more of an electric motor of the vehicle, one or more other electric vehicle, and/or other sources that may need electrical energy.

FIELD

This disclosure relates to generally to load banks, and in particular, to apparatuses, systems, and associated methods for configuring a portable load bank apparatus to utilize waste energy into battery charging for electric vehicles.

BACKGROUND

Load banks are testing devices that are used to simulate artificial electrical loads for the purposes of establishing proper and correct operation of power sources, such as generators and the like. A load bank tests these power sources by developing an electrical load. Various load configurations permit testing under different conditions. Load banks ensure the quality and reliability of the power output of power sources. Power may be measured as the rate, per unit time, at which electrical energy is transferred by an electric circuit. Load banks are used to verify the accuracy of output capacities by creating a variety of different loads that replicate real-world use. Some regulated institutions, such as hospitals, are required to test their power sources on a regular basis.

SUMMARY

The electrical power that is delivered to the load bank from a power source during a load test is typically converted into thermal energy at the load bank, and dissipated by rapid cooling using large fans to provide airflow. This is because a load bank typically services one purpose—to test the power source. The thermal energy dissipated by a load bank as a result of its typical use represents power that was, aside from the testing purposes, wasted.

Conventionally, load banks may be carted on a trailer towed by either a small commercial vehicle, or, in larger capacities, by large semi-trucks. A load bank operates independently, and after completion of a load test, is usually towed or driven back to the home base or next testing site. This requires the use of a fossil fuel powered vehicle to either tow the load bank on a trailer, or have it loaded onto a truck.

One or more implementations of the present disclosure propose a specially configured portable electric load bank apparatus, system, and method of operation, that solves an unmet need in the load bank and power source testing industry—utilizing the wasted energy. In particular, an apparatus of the present disclosure may comprise a load bank that may be permanently mounted on an electric commercial vehicle (“ECV”), such as a Semi-Trailer, Electric Powered Utility Vehicle, or the like. The load bank may comprise a combination of resistive/reactive components, capacitive components, and/or other components. Also mounted on the ECV may be a set of batteries. The batteries in the set of batteries may be the same as, or similar to, power sources that are used for the propulsion of electric vehicles. A function of the ECV may be to transport the mounted load bank from jobsite to jobsite, as well as use the waste energy to charge its own batteries and other batteries that may be used for charging other electric vehicles and/or other batteries and/or battery powered equipment (e.g., drones, bicycles, residential and/or commercial battery power storage, etc.). Accordingly, at least one of the battery sources may be used for the propulsion of the ECV. In the case of the semi-trailer type vehicle carrying a larger load bank, an addition of a fossil fueled generator may be mounted for contingency purposes.

A High Voltage Direct Current (“HVDC”) charger may be used in combination with a Level 2 EV charger (and/or other use-specific battery chargers) and mounted on the ECV. The HVDC charger may derive its input voltage from the power source being tested through the load bank. The apparatus may be configured to determine an optimal charging power (e.g., rate, current, and/or voltage) and/or electrical energy to charge one or more of the batteries.

A specific simulated artificial load may be requested for the load bank from a power source being tested, so that the power source outputs electrical power that meets the requested load. The distribution of the output electrical power from the source may be determined such that electricity may be directed to flow to one or more chargers (to charge batteries) and/or the load bank (to dissipate as heat). The distribution may be based on priority, e.g., to one or more of the chargers for charging batteries for storage (and later charging of one or more external batteries), and/or for self-consumption (e.g., charging one or more batteries used specifically for powering an electric motor of the apparatus). By way of non-limiting illustration, an onboard computer may be configured to determine the required charging power (and/or energy) to charge the set of batteries and to apply a portion of the output electrical power (and/or energy) to the HVDC charger to charge the set of batteries. Any electrical energy over and above the requested charging power (in accordance with the artificial load requested) may be distributed amongst the resistive/reactive/capacitive components of the load bank and dissipated as thermal energy. Once the set of batteries have been satisfactorily charged to optimum capacity by the waste energy, the apparatus may utilize an EV charger to charge other EVs, other vehicles having batteries, and/or other battery storage devices. Depending on the amount of waste energy available, and/or the required energy (e.g., kWh) to replenish the set of batteries, a DC/DC converter may be used to supercharge EVs, should excess waste energy be available.

The ECV can now travel under its own propulsion to its following destination. The available travel range of the ECV may be determined. The apparatus may be configured to determine the amount of electrical power (and/or energy) required to reach the next destination of the ECV. Should the available range be further than the power (and/or energy) required to reach the destination (e.g., with a factor of safety or buffer for slow traffic, etc.) the residual battery power may be used for charging other EVs and/or other battery storage from the apparatus. The range needed to travel to the next destination, plus contingency range, may be essentially a zero-level of charge. In the event of a range miscalculation due to extenuating circumstances, a generator may be used as a backup. The energy being produced by the generator to increase the range may be metered and logged to establish wasted energy from sacrificial energy. In medium voltage applications, a generator traditionally used for fans and/or controls may be replaced with a set of battery packs with alternating consumption and charging, respectively. One or more implementations of the apparatus presented herein may solve a problem of using equipment at higher elevations where a diesel generator would be derated.

One or more implementations of a system presented herein may include one or more of a vehicle, a load bank, set of batteries, a set of battery chargers, one or more processors configured by machine-readable instruction, non-transitory electronic storage, server(s), computing platform(s), external power source(s), and/or other components. One or more of the components of the system, when mounted to the vehicle, may form a “portable load bank apparatus” of the present disclosure.

The load bank may be configured to cause an external power source to generate a power output as part of a load test of the external power source. The set of batteries may be configured to store electric energy. The set of batteries may be electrically coupled to the load bank and/or other components. The set of battery chargers may be configured to direct the flow of electricity to the set of batteries. The set of battery chargers may be electrically coupled between the load bank, the set of batteries, and/or other components.

The non-transitory electronic storage may include storage that is integrally coupled with a vehicle, included with a remotely located server, included in one or more computing platforms that communicate with the vehicle and/or server, and/or included in other locations. The one or more processors may include one or more of processor(s) integrally coupled with a vehicle, processor(s) of a remotely located server, processor(s) of one or more computing platforms, and/or other components.

The one or more processors may be configured by machine-readable instructions. Executing the machine-readable instructions may cause the one or more processors to facilitate control of a portable load bank to utilize waste energy into battery charging. The machine-readable instructions may include one or more computer program components.

A computer program component may be configured to obtain a request for power output by the external power source, as part of a load test by the load bank. The electrical energy from the power output may be obtained at the load bank, through an electrical coupling of the external power source and the load bank.

A computer program component may be configured to cause one or more battery chargers in the set of battery chargers to direct an amount of the power output obtained by the load bank to the set of batteries. The amount of the electrical energy from the power output directed from the load bank to the set of batteries may comprise a battery input power (and/or energy). The battery input power (and/or energy) may comprise the electrical energy that charges the set of batteries, either to a complete charge or other charged state.

A computer program component may be configured to cause a remaining power (and/or energy) from the power output to be converted to thermal energy by directing the energy to the load bank for dissipation as heat. The remaining power (and/or energy) may be measured as the power output less the battery input power (and/or energy).

The non-transitory electronic storage 118 may include storage that is integrally coupled with a vehicle, included with server(s) 122, included in one or more computing platforms 126, and/or included in other locations. The non-transitory electronic storage 118 may store information utilized by one or more components of the system 100. By way of non-limiting illustration, the information may include computer program components and/or other information.

The one or more processors 104 may be configured by machine-readable instructions 106. Executing machine-readable instructions 106 may cause one or more processors 104 to facilitate controlling a portable load bank apparatus 101 and/or other components. The machine-readable instructions 106 may include one or more computer program components. The one or more computer program components may include one or more of a testing component 108, a charging component 110, and/or other components.

The testing component 108 may be configured to obtain a request for power output by external power source(s) 125, as part of a load test being performed by the load bank 121. By way of non-limiting illustration, a display may be configured to present a user interface through which a user may submit a request for power output. The request may include one or more of an amount of the power output, timing of the power output (e.g., when to start, when to stop, etc.), and/or other information.

The testing component 108 may be configured cause the external power source to generate electricity as part of a load test of the external power source. In response to the request, the external power source(s) 125 may be activated such that a power output may be generated. By way of non-limiting illustration, submission of the request may cause the sending an electrical signal (e.g., duty cycle commands corresponding to a desired load) to external power source(s) 125 which causes the external power source(s) 125 to be powered “on.” The power output may be obtained at the load bank 121, through an electrical coupling of the external power source(s) 125 and the load bank 121.

The charging component 110 may be configured to cause one or more battery chargers in the set of battery chargers 123 to direct an amount of the power output obtained by the load bank 121 to the set of batteries 119. The amount of the power output directed from the load bank 121 to the set of batteries may comprise a battery input power (and/or energy). The battery input power (and/or energy) may comprise the electrical energy that charges the set of batteries 119, either to a complete charge or other charged state. It is noted that while some descriptions herein describes the distribution of electricity as a measure of power (e.g., rate, per unit time, at which electrical energy is transferred), this is for illustrative purposes only. Those skilled in the art may appreciate that the distribution may alternatively and/or concurrently be based measures of electrical energy, and/or other measures.

In some implementations, the charging component 110 may be configured to determine the battery input power (and/or energy) based on a current state of charge of the set of batteries 119. By way of non-limiting illustration, a current state of charge of the set of batteries 119 may be measured through a battery monitoring system (not shown in FIG. 1 ). One or more of voltage, amperage, and/or ampere hours remaining may be measured through a battery monitoring system (BMS) and/or apparatus suitable for the intended purpose. The battery monitoring system may be integrally coupled to the vehicle(s) 102. The BMS may prevent operation outside the set of batteries 119's safe operating area. By way of non-limiting illustration, a BMS may include one or more of an internal switch (such as a relay or solid state device) which is opened if a battery is operated outside its safe operating area, ability to request the devices to which a battery is connected to reduce or even terminate using the battery, ability to actively control the environment (e.g., such as through heaters, fans, air conditioning or liquid cooling), and/or other features and/or functionality.

In some implementations, the charging component 110 may be configured to determine an amount of travel power (and/or energy) the portable load bank apparatus 101 may need to reach a destination. The charging component 110 may be configured to determine the battery input power (and/or energy) based on the amount of travel power (and/or energy), so that the amount of charge of one or more batteries may be sufficient to supply the amount of travel power (and/or energy).

In some implementations, the charging component 110 may be configured to cause a remaining power (and/or energy) from the power output to be converted to thermal energy by the load bank 121 and/or other components, and dissipated as heat. The remaining power (and/or energy) may be measured as the power output less the battery input power (and/or energy). Through the active charging of batteries using the power output from an external power source, the portable load bank apparatus 101, and/or system 100, is now able reduce the amount of “waste” energy that is the consequence of load tests.

In some implementations, the testing component 108 may be configured to obtain an indication that the load test is complete. The indication may be derived from one or more of a duration of the load test ending, a predetermined amount of energy being supplied (e.g., kilowatt-hour output being reached), and/or other indications.

The testing component 108 may be configured to cause a reduction in the power output by an external power source. In some implementations, the external power source's output may be slowed reduced in power for safety reasons and/or for the proper functioning of the source. Upon reaching a safe or predetermined reduced power output, the testing component 108 may be configured to cause the load bank 121 to be shut down. Upon reaching a safe or predetermined reduced power output, the testing component 108 may be configured to cause the external power source to be shut down. In some implementations, causing actions at the external power source may be accomplished through control signals or commands being generated and sent from the processor(s) 104 to the external power source.

By way of non-limiting illustration, a 100 kW load on the load bank 121 from a generator. Traditionally, the entire 100 kW would be dissipated as heat from a load bank during and/or after a test. Now, with the portable load bank apparatus 101 and/or system 100, at least some (if not all) of that energy can be utilized to charge one or more batteries. Those batteries, in turn, may power an electric vehicle carrying the load bank 101, other electric vehicles that need a charge, and/or other batteries. By way of non-limiting illustration, from that 100 kW that is requested, 25 kW (or other amount) may be delivered to an HVDC charger to charge one or more batteries, while the other 75 kW (or other amount) may be dissipated as heat. These values are provided for illustrative purposes only and are not to be considered limiting.

FIG. 4 illustrates a portable load bank apparatus 400, in accordance with one or more implementations. Also shown is an external power source 402, such as a generator that may require load testing.

The elements shown using reference numerals 404 to 412 refer to components that may be integrally coupled (e.g., mounted) within, on, or otherwise to, vehicle 401. The presentation of those elements above and outside of vehicle 401 is merely provided for illustrative purposes as those elements are intended to be integrated with vehicle 401. The solid lines represent preferred electrical coupling between components; however, other coupling arrangements/schemes may be employed.

One or more functions of computer program components described herein may be one or more of software-implemented, hardware-implemented, and/or software and hardware-implemented. The description of the functionality provided by the different components 108 and/or 110 described above is for illustrative purposes and is not intended to be limiting, as any of components 108 and/or 110 may provide more or less functionality than is described. For example, one or more of components 108 and/or 110 may be eliminated, and some or all of its functionality may be provided by other ones of components 108, 110, and/or other components.
